Commitments and Contingencies</b> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt">In the ordinary course of conducting business, our subsidiaries are involved in various legal proceedings, either indirectly as insurers for parties or directly as defendants. Most the these proceedings are claims litigation involving our subsidiaries as either (a) liability insurers defending or providing indemnity for third party claims brought against insureds or (b) insurers defending first party coverage claims brought against them. We account for such activity through the establishment of unpaid loss and loss adjustment reserves. Our management believes that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and cost of defense, will not be material to our consolidated financial condition, results of operations, or cash flows. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt">Our subsidiaries are also from time-to-time involved with other legal actions, some of which assert claims for substantial amounts. These actions include claims asserting extra contractual obligations, such as claims involving allegations of bad faith in the handling of claims or the underwriting of policies. In general, we believe we have valid defenses to these cases. Our management expects that the ultimate liability if any, with respect to future extra-contractual matters will not be material to our consolidated financial position. Nonetheless, given the large or indeterminate amounts sought in certain of these matters, and the inherent unpredictability of litigation, an adverse outcome in such matters could, from time-to-time, have a material adverse outcome on our consolidated results of operations or cash flows in a particular fiscal quarter or year. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Includes disclosure of commitments and contingencies.
